Ephedra cultivation technology

Ephedra is a traditional Chinese herbal medicine. The herbaceous stems have functions of sweating, coughing, relieving asthma, and benefiting water. They can treat exogenous cold, cough, and emphysema. The economic benefits are considerable. In recent years, due to the pursuit of high efficiency, the unreasonable exploitation of wild ephedra resources has led to the depletion of resources. In this regard, the state has explicitly prohibited the exploitation of wild ephedra resources. Therefore, whether cultivated ecologically or economically, artificial cultivation of ephedra plays an important role in adjusting the structure of the agricultural industry and increasing farmers' income. The planting techniques for ephedra are described below for reference.

The acquisition targets are also the main varieties cultivated.

Farmyard fertilizer 2000 kg, superphosphate 15 kg. Pour well overwinter water at the end of October. Ephedra is a perennial herb, often accompanied by a variety of weeds, competes with ephedra for water, and competes for fertilizers. It has a great influence on the amount of grass production and alkali production of ephedra. Therefore, we must pay attention to weeding and weeding. Make sure there is no weed growth in the ground.

6. Insect pests and insects that damage ephedra are mainly locusts. If they are found to be parasitized in fields, they should be sprayed with chrysanthemum oil 1000 times.
